    Hi all,
    Broke my head setting up Darkcoin mining on 2x7950 rig.
    Tried different core/mem clocks hashrate is fine (up to 1600 mh per card) but still not a single accepted share - HW errors only
    [​IMG]
    My config:
    Code:
    {
    "pools" : [
    ],
    "kernel" : "darkcoin",
    "gpu-threads" : "2",
    "worksize" : "256",
    "lookup-gap" : "2",
    "shaders" : "1792"
    }
    
    also tried variety of thread-concurrency and intensity values
    Code:
    "thread-concurrency" : "8192",
    "intensity": 13
    
    Any thoughts on what's wrong ?

    Thanks !

    Thread concurrency and shaders together are useless, just use one of them.
    Try to lower clock and memory speed and check if anything changes

    Tried that with no change at all.
    Not a single accepted share.

    1 - exactly what version miner are you using?
    2 - OS, driver version
    3 - card brand?
    4 - full config file please !! (hide personal info if you're paranoid)

    try only 1 gpu thread, and work 128 (one at at time). I know it sounds nuts, but my x11 config is completely different to my scrypt config. I'm using intensity 19 for MPOS and 18 for p2pool for example. This is insane under scrypt.
